  • Structure and History of Hellenides
    Argyriadis, I. and Forti, S., 2016. Structure and history of Hellenides. Boletín Geológico y Minero, 127 (2/3): 575-592 ISSN: 0366-0176 Structure and history of Hellenides Ion Argyriadis(1) and Silvia Forti(2) (1) Cabinet de Géologie Argyriadis, 975 chemin du Pré de Caune, 83740 La Cadière d’Azur, France [email protected] (2) Via Verseiner 44/B, Meltina, 39010 Italia [email protected] ABSTRACT This study is based on some new field observations made on the group of the Eastern Hellenic regions. Our observations have led us to adopt a simplified view of the paleogeography of the Greek mainland before the Alpine orogenesis. The subsequent varied tectonic units originate mainly from the following paleogeo- graphic areas: • A carbonate Arabo-African shelf margin which displays several lateral transitions, ridges and basins. On the Greek mainland this margin is represented by the Preapulian, Ionian, Gavrovo-Tripolis, Parnassos zones, the Olympus platform and probably the Kavala and Thassos marble. • A transition zone from the shelf units to the Tethys ophiolites (Pindos Zone, Styra, Argolis and Hydra, Eretrias new unit). • Tethys ophiolites, which might represent either an “ocean” fault zone or subduction of the lithosphere along a weak area. • A Hercynian continental mass (Serbomacedonian). This group is currently completed by the presence of a large tectonic mélange connected to the ophiolite overthrust. Key words: Hellenides, structural geology, ophiolites emplacement, actualism Estructura e historia de las Helénides RESUMEN Recientes trabajos de campo nos permiten llegar a una nueva lectura del conjunto de datos así como a la nue- va interpretación que resulta de los mismos Distinguimos por ende, para el conjunto de las Hellenidas, cinco unidades paleo-geográficas mayores, escalonadas entre Paleo África y Europa, quiénes, mediantes fases tectónicas superpuestas - y no paralelas, ni tampoco de igual desplazamiento, conformaron el edifico actual: • Una plataforma carbonatada arabo-africana, incluyendo variaciones laterales y longitudinales.

The smoke of the fire of Kineta as seen in the center of Athens at 13:08 Fire weather and vegetation condition • According to weather measurements at the National Observatory of Athens on Mt.

All balanids, regardless of their solitary or clustered lifestyle, are post-mortem transported, abraded and/or bioeroded, and deposited in offshore tempestites during high-stand pulses. The burrows of the callianassid shrimp Upogebia, and of the ghost crab Ocypode, indicate short-termed, extremely shallow sub- to intertidal low-stand pulses. The whole sequence, be- ing the uppermost part of the ‘post-Pikermian’, Lower Pliocene (Zanclean) marine overflood, is composed of three, successively thinning, shallowing-up cyclothems, topped by sub- to intertidal and/or emersive episodes, the last of which is featured by beachrock horizons that terminate the regressive events preceding an encroachment of the potamogenic (fluvial and/or deltaic) regime. Key-words: Regressive cyclothems, Balanid cirripedes, Eco-taphonomy, Burrows, Mass burial, Fossillagerstätte, Pliocene, Greece.

  • Air Quality Impacts Caused by the Transfer of the Athens Airport from Hellenikon to Spata A.G
    Transactions on Ecology and the Environment vol 6, © 1995 WIT Press, www.witpress.com, ISSN 1743-3541 Air quality impacts caused by the transfer of the Athens airport from Hellenikon to Spata A.G. Proyou, N. Moussiopoulos, K. Karatzas Laboratory of Heat Transfer and Environmental Engineering, Aristotle University Thessaloniki, 54006 Thessaloniki, Greece Abstract Aim of this paper is to study the air quality impacts due to the transfer of the Hellenikon airport to the region of Spata. Air pollutant emissions associated with the airport operation are firstly discussed. Mean monthly air pollutant concentrations (CO and NO%) are estimated with the Gaussian Model PAL, both for the "do nothing" scenario and the assumption of the airport in operation for the areas of Hellenikon and Spata. Results indicate that the installation of the new airport out of the Athens basin will improve the air quality in the basin. The operation of the Spata airport will lead to considerable air pollution levels in the area that will increase up to the year 2012. Nevertheless, the existing air quality standards or targets are not expected to be exceeded with the only eventual exception of the NC^ levels. 1 Introduction The present work deals with the impacts on air quality from the planned transfer of the Hellenikon airport to the region of Spata. For this purpose, emissions related to the operation of the airport of Spata were estimated and concentration levels were calculated for the years 2002 and 2012. For comparison, calculations were carried out also for the airport of Hellenikon for the present situation (1993) and the years 2002 and 2012.
